CURTAIN-POLE.

Specification of Letters Patent.

Patented Feb. 12, 1918.

fl '0 all whom it may concern:

Be it known that We, EDWARD B. FARGO and GLEN R. CASE, citizens of the United States, res ding at the city of Clintonville, county of -Waupaca, and State of Wisconsin, have invented new and useful Improvements in Curtain-Poles. of which the following is a specification.

Our invention relates to improvements in curtain poles.

The object of our invention is, first, to provide a device for quickly and easily attaching a curtain to a pole in such a manner that the curta n is not liable to become accidentally detached when enrolled; second to provide a device for causing the core and rod to revolve with the inclosing pole. which end is accompl shed by providing a lo gitudinal groove, in the eXtel'ior tubing of which the pole is formed which registers with and extends down into a corresponding; longitudinal groove formed in a removable spring retaining core, in which a spring supporting rod is inclosed; and third. to the construction of the dev ce, whereby in case said spring becomes broken or defective the same can be readily withdrawn with the core and rod. when said spring may be replaced by another.

Our invention is further explained by reference to the accompanying drawing, in which Figure 1 represents the curtain as it appears secured between the foldable edges of a piece of sheet metal before attaching the same to the curtain pole.

Fig. 2 represents a front view of the curtain pole, part in section with. the rod and curtain attached.

Fig. 3 is a longitudinal section of a portion of the pole, showing the manner of supporting the spring inclosing core and spring supporting rod.

Fig. 4 is a transverse section, drawn on line 4, l of Fig. 2, and

Fig. 5 is a transverse section, drawn on line 5, 5 of Fig. 2.

Like parts are identified by the same ref-- erence numerals throughout the several views.

1 represents the curtain. one end of which is first secured between the folded edges 2', 2' of a piece of sheet metal 2, when the metal is punctured or perforated. as shown at 3, whereby the curtain is securely retained between said folded edges. as shown in Fig. 4. 4 is a curtain pole which is formed of sheet metal, and said pole is preferably formed in two pieces 5 and 6, which are to]- escoped together, as shown in Fig. The pole 4 is provided with a longitudinal groove 7 formed for the reception of the sheet metal 2, which sheet metal 2 is placed in said groove. when it is thus retained in place by a plurality of rings 8. The ends 9, 9 of the rings 8 terminate at slight dis tances apart. as indicated in Fig. 4. whereby when said rings are turned on the our tain pole the space 10 between the ends 9. 9 may be brought directly above the groove 7, whereby the folded sheet metal 2, which en ages the end of the curtain may be readily inserted in said groove. as shown in Fig. l, when said rings are again turned on said pole so that one of the ends of the rings will be brought above the folded sheet metal 2, whereby the end of the curtain l is securely retained in place.

Centrally located in the pole 4 is a eylin drical core 11, which is formed for the reception of the spring 12 and spring supporting rod 13. One end of the rod 13 is provided with a cylindrical block 14. which is secured in place in said core ll by the nail 15, as shown in Fig. 3. The outer end of the rod 13 is connected with the fixed member 16 by or through the end of the spring 17, and said groove 7 extends down into the core 11, as shown in Figs. 4 and 5), whereby said core is caused to revolve with the curtain pole as the curtain is wound thereon and unwound therefrom, whereby motion will be communicated from the inclosing pole 4 to said core. and from thence to said rod and one end of said spring, independently ot' the action of said nail. Said groove 7 cooperates with said nail to secure said core and pole to rether.

It will now be obvious that when the cur tain is unwound by being drawn downwardly a revoluble movement will be communicated therefrom to said pole, whereby said spring will be wound up in the ordinary way, and whereby when said curtain is released said pole will be caused to revolve in the opposite direction by the recoil oi said spring.

It will also be obvious that should said spring 12 become broken or otherwise defective it can be readily removed from the pole,

lit)

together with the core 11, when said spring may be replaced by another without disturbing the curtain or other parts of the curtain pole. Each end of the pole 4. is pro vidcd with an inclosing ring 18, as shown. in Fig. 2. and said inclosing ring is located outside of the vertical edge of the curtain 1, whereby said curtain and the bars 2, to which it is :ttaehed, are prevented from moving longitudinally on said pole. It will be understood that the rings 18, 18. located at the respective ends of the curtain pole. as shown in Fig. 2, are located outside of the edge of the curtain and are contiiuious solid rings, while the rings 8, S, 8, located between said end rings 18 serve to hold the plate 2 and the end of the curtain securely in the groove of the curtain pole. The object of the rings 18 is to prevent movement of the curtain and curtain retaining plate and also to prevent the rod from telescoping. while the object of the intermediate rings 8, which are adapted to be turned above the plate 2. is to retain said plate 2 and the curtain in place. Thus, it is obvious that the pole and curtain retaining members do as a matter of fact cooperate, and neither would work without the other.

Having thus described our invention what we claim as new and desire to secure by Letters Patent, is

1. In a device of the described class, the combination of a. curtain pole, a curtain, a. removable core. a spring and spring supporting red removably located within said core. said pole and core being provided with a longitudinal groove, the groove of said pole being located within the groove of said core, whereby said pole and core are adapted to revolve together, a foldable bar adapted to be clamped to one end of said curtain and located within said longitudinal groove, and a plurality of rings inclosing said pole at intermediate points between its respective ends, said rings being adapted to be turned a partial revolution on said pole so as to hold the end of said curtain and its retaining members in said longitudinal groove.

2. In a device of the described class, the combination of a curtain pole a curtain, a removable core, a spring and spring sup porting rod removablv located within said core, said pole and core being provided with a. longitudinal groove, the groove of said pole being located within. the groove of said core, whereby said pole and core are adapted to revolve together, a. oldable bar adapted to be clamped to one end of said curtain and located within said loi'igitiulinal groove a pair of annular rings one located at. each end of said pole between the outer edge oi said curtain and the ends ot said pole, and a plurality of rings inclosing said pole at intermediate points between its respectiveends, said rings being adapted to be turned a partial revolution on said pole so as to hold the end of said curtain and its retaining members in said longitudinal groove.

In testimony whereof we aliix our signatures in the presence of two witnesses.
